2 Claims.

My invention relates generally to beds, and

more particularly to a sheet that is constructed so as to function as amattress cover, and one of the principal objects of my invention is, toconstruct a bed-covering sheet wherein the main body portion is composedof a single piece of fabric cut to proper shape and having its cornersunited by stitching or otherwise, so as to form depending portions thatoverlie the sides and ends of a mattress and also portions that extend ashort distance inwardly onthe under side of the mattress from the sidesand ends thereof, thus providing a. covering sheet that will retain itsposition on the mattress, and which sheet, in use, will not pull andwrinkle as a result of movements of the occupant of the bed of which themattress forms a part.

A further object of my invention is, to provide a mattress-coveringsheet that may be easily and quickly applied to or removed from themattress,

thereby effecting a material saving of time and labor in making up beds,which consideration is especially important in hotels, hospitals and thelike, where a large'number of beds are in use.

A further object of my invention is, to construct amattress-covering'sheet, and particularly the sides, ends and cornersthereof, so that the latter will fit neatly without wrinkles over thesides and ends of the mattress.

With the foregoing and other objects in view, my invention consists incertain novel features of construction and arrangements of parts thatwill be hereinafter more fully described and claimed and illustrated inthe accompanying drawing in which:

Figure 1 is a. plan view of the mattress-covering sheet, cut to propershape and illustrating the same as it appears before the corner edgesare sewn together to form the side and end covering portions.

Figure 2 is a perspective view looking against the under side of amattress to which one of my improved sheets is applied.

Figure 3 is a cross section taken on the line 3-3 of Figure 2.

Figure 4 is a detail view looking against the under side of one of thecomers of the mattresscovering sheet.

Figure 5 is a perspective view of a modified form of the cornerconstruction.

Figure 6 is a detail view of a modified form of that portion of thesheet that underlies the mattress.

As illustrated in Figure 1, the main body por- (Cl. 5-354) n Y tion ofthe mattress-covering sheet is formed from a single piece of fabric,substantially rectangular in shape and this;single piece of materialcomprises a rectangular portion II) that corresponds in size and shapeto the top of the mattress to which the sheet is to be applied andportions I I of the fabric forming the main body portion In constituteside strips that are adapted to overlie the sides of the mattress.correspond-- ing portions I! at the ends of the main body portion in ofthe fabric constitute strips that are adapted to overlie end faces ofthe mattress.

Between the side and end covering portions II and i2 and the outer edgesof the fabric utilized in producing the mattress cover, narrow portionsl3 of the fabric constitute strips that are adapted to extend inwardlyfrom the lower portions of the side and end covering strips H and I2 andto lie immediately beneath the under face or surface of the mattress.

To produce the side and end covering portions H and i2 and theunderlying portions It, the corners of the rectangular piece of fabricfrom which the covering sheet is formed are cut away on diagonal linesdesignated by it, and which lines are disposed at 45 relative to theside and end edges of the sheet and intermediate the endsof the inclinededges Hi, the fabric is cut away to form notches 85, the edges i6 01'which are respectively parallel with the side and end edges of thefabric from which the covering sheet is formed.

After the fabric has been cut to the shape as just described, and asillustrated in Figure. 1, the, edges it of the notches I 5 are broughttogether and stitched and likewise the edges 14 are brought together andstitched, with the result that when the covering sheet is completed, theportions II and I 2 overlie respectively the sides and ends of themattress and the portions I3 underlie those portions of the mattressimmediately adjacent the side and end faces thereof.

In order to strengthen the corners between the underlying portions l3 ofthe cover, substantially triangular gussets ll, of material somewhatheavier than the material from which the sheet is formed, are insertedin the corners between the inner edges of the underlying strip portionsl 3 and to accommodate a certain amount of pulling strains withouttearing, these gussets I! may cover without the gussets [1.

Instead of forming the main body portion of the sheet from a singlepiece of material, my invention contemplates the construction of acovering sheet having separately formed corner portions that aresuitably secured. to the corners of the main body of the sheet, asillustrated in Fig. and further, the members it that underlie themattress may be connected with lacings or with longitudinally ortransversely disposed straps.

In order to take up any slack that might develop in the underlyingportions i3 of the cover, substantially V-shaped portions may be cutfrom the intermediate portions of said underlying members and the edgesof the material at the sides of the cut-away portions brought togetherand stitched so as to cause the underlying portions to lie practicallyflat. against the under side of the mattress. (See Fig. 6.)

Further, the covering member constructed in accordance with my inventionmaybe utilized as a cover for cots, day beds, surgical tables, palletsand the like, and also as a cover for benches, tables and other piecesof furniture.

A sheet of my improved construction may be easily and quickly applied toor removed from a mattress, and when properly positioned therevupon, thesides and ends fit neatly over the side and end faces of the mattressand the main body portion ill of the sheet is maintained in smoothcondition on the upper surface of the mattress.

Inasmuch as the main body portion of my improved mattress-covering sheetis formed from a single piece of fabric, a material saving of time,

labor and consequent expense in the manufacture of the covering sheetsis effected.

Thus it will be seen that I have provided a.

mattress-covering sheet that is relatively simple in construction,inexpensive of manufacture and very effective in performing thefunctions forwhich it is intended.

It will be understood that minor changes in the size, form andconstruction of the various parts of my improved mattress-covering sheetmay be made and substituted for those herein shown and described withoutdeparting from the spirit of my invention, the scope of which is setforth in the appended claims.

I claim as my invention:

-l. As a new article of manufacture, a mattress covering sheet,comprising an inverted boxlike member having a closed top for coveringthe upper surface of a mattress, depending end and side walls to coverthe sides and ends of said mattress and inwardly directed extensions ofthe elongated free edges of said end and side walls underlying marginalportions of the bottom of said mattress, said extensions beingtrapezoidal in plan, adjacent ends of said extensions being connected toprovide a continuous rectangular flange, and a resilient reinforcinggusset at each corner of said flange, straight edge portions of saidgussets extending across said corners inwardly thereof.

2. As a new article of manufacture, a mattress covering sheet,comprising an inverted box-like member having a closed top for coveringthe upper surface of a mattress, depending end and side walls to coverthe sides and ends of said mattress and inwardly directed extensions ofthe elongated free edges of said'end and side walls underlying marginalportions of the bottom of said mattress, said extensions beingtrapezoidal in plan, adjacent ends of said extensions being connected toprovide a continuous rectangular flange, and a resilient triangularreinforcing gusset at each corner of said flange, the bases of saidgussets extending across said corners inwardly thereof.
